Apple has set a new deadline of November 1, 2026 for all Patreon creators to switch from Patreon's legacy billing system to the App Store's in-app purchase system in the Patreon app on the iPhone and iPad, as reported by TechCrunch. Note: This image has been edited to include a pile of cash. Patreon is a platform where creators such as YouTubers can receive payments from fans, which can be a valuable revenue stream alongside ads and sponsorships.
I think the app already encourages you to pay via the site instead of in-app which a few other apps do as well but maybe not as high profile as Patreon. Apple is probably going to delist the app altogether which is fine because it sucks anyway.
